稻田综合种养模式能够从源头减少氮、磷的输入,提高稻田系统的养分利用率.在紫云英全量还田的基础上,设计了多物种参与下的稻鸭复合种养模式,通过与常规稻作对比,养萍处理与不养萍处理的对比,从稻鸭复合系统中氮、磷的输入与输出途径出发,分析了氮、磷在系统中的迁移与循环特征,以及萍类对氮、磷的迁移与循环的影响.

The integrated cultivation mode of paddy field can reduce the input of nitrogen and phosphorus from the source and improve the nutrient utilization rate of paddy field system. Based on the total amount of astragalus sinensis returned to the field.a rice - duck hybrid cultivation model with multi - species participation was designed. By comparing with conventional rice cultivation .the treatment of raising duck with that of non - raising duck was compared. Starting from the input and output routes of nitrogen and phosphorus in rice - duck complex system,the migration and circulation characteris...
